Cultivar Notes - 'Cobweb Buttons'
One of the most distinctive types of Sempervivum. Aptly named, 'Cobweb' is covered with fine, white threads which crisscross between the leaves' tips like a cobweb. Each rosette of pointy, blue-green leaves grows about 1 inch wide. Their color may vary from season to season. Unusual rose-pink flowers are produced on leafy stalks in midsummer.
Genus Notes - Sempervivum
Hens and Chicks, a touch of nostalgia!
Once, every grandchild received a start of this plant from their grandmother. Rosettes of leaves (the hens) send out many offsets (the chicks) which can be pulled off and transplanted. Prefers sun in almost any soil. Unusual flowers spikes are produced eventually. A resurgence of interest has Sempervivums used in living wreaths, spilling out of clay pots, old tea kettles, and even retired work boots.
All derive from alpine species native to the mountains of southern Europe and western Asia. The rosettes develop by long-stalked offsets into crowded, colorful, richly textured mats. In summer the older rosettes send out thick upright stems bristling with stubby pointed leaves and topped with dense clusters of tightly packed pink blooms. Rosettes die after flowering.
